Feeling tired after waking up every day is mostly a sleep disorder caused by poor sleep quality at night, reduced deep sleep time or excessive dreaming time, which is a kind of insomnia. Insomnia is a subjective experience in which the quality or quantity of sleep does not meet normal physiological needs due to difficulties in falling asleep and/or maintaining sleep, thus affecting daytime social functioning. Insomnia includes various forms such as difficulty falling asleep, early awakening, excessive dreaming during sleep, and difficulty falling asleep after waking. For this condition, new non-benzodiazepine sedative-hypnotic drugs such as dexrazopiclone can be considered, which can adjust the sleep structure and shorten the sleep latency, resulting in less dreaming time and more deep sleep time. Melatonin receptor agonists, such as Remelaton, can also be taken for the same effects described above.
